Origin & Breeding History: 'RIKAV17805' was developed by the breeder, Rika Tsutsumi, in Higashiomi, Shiga, Japan, as part of a controlled breeding program for Plant 21 LLC. It originated from a cross conducted on May 5, 2010 between variety '08V603-01' as the female parent, and the proprietary line designated '09V852-01' as the male parent. 'RIKAV17805' was selected from the resulting progeny in Bonsall, California, USA, on June 9, 2011, based on its plant growth habit and vigour, flower colour, good branching, leaf colour and improved disease resistance. 'RIKAV17805' was first propagated by vegetative tip cuttings on June 10, 2011.

Tests & Trials: The trial for 'RIKAV17805' was conducted in a polyhouse during the summer of 2013 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings transplanted into 15 cm shallow pots on June 26, 2013. Observations and measurements were taken from 10 plants or parts of plants of each variety on July 31, 2013. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
